Abstract

The method of providing an improved soldered electrical connection includes the step of providing a ring over an electrical wire and a terminal which are to be soldered together, and then compressing the ring to form a mechanical connection between the wire and the terminal prior to soldering. The mechanical connection holds the wire for a substantial length against the terminal and prevents movement during the soldering thereby insuring against a cold solder joint. Preferably, the ring is divided with the free ends preferably being offset to provide ease in sliding past each other. Preferably, a specially designed tool is utilized to compress the ring, the tool being provided with specially designed grooves in its jaws for holding the ring on end.
